Professional Insulated Motor Bearings Replacement Aluminium Oxide Coating

Electrically Insulated Bearing 6215 M/C4VL0241 Bearing 75×130×25mm Used In Traction Motors

In most cases, it is sufficient to interrupt the electric circuit between the housing and shaft, in order to mount Electrically Insulated Bearing at one or both bearing locations, depending on the application.

Generally, Electrically Insulated Bearing 6215 M/C4VL0241 (ceramic-coated ) exhibit significantly higher resistance to electrical current than standard bearings.

Electrically Insulated Bearing 6215 M/C4VL0241 is Deep Groove Ball Bearing design. its dimension is 75×130×25mm, it has the same dimension and the same design with normal chrome steel 6215 bearing. but the most different is 6215 M/C4VL0241 bearing with Aluminium Oxide Coating . the coating can Electrical Resistance Voltages up to 3000 V DC.

A much more economical solution is to provide for the use of Electrically Insulated Bearing 6215 M/C4VL0241 during the planning stage. This reduces maintenance and repair costs and increases machine availability – all of which means greater value for the customer.

Electric motors, generators and associated equipment are at risk when an electric current passes through their bearings. This can damage the contact surfaces of rolling elements and raceways in the bearings (electrical erosion) and rapidly degrade the grease. An additional risk in electric motors and generators comes from high-frequency currents caused by the inherent stray capacitance. The risk of damage increases where the application uses a frequency converter.
